West 2300 1/32 DIN Indicator and Controller
Product Core Overview
The West 2300 is a 1/32 DIN specification multifunctional device that combines indicator and controller functions. It is compact in size but fully functional. Equipped with a 10mm high large display screen (optional in red or green), built-in 2A relay, supports full 3-wire PT100 input, and the controller version is also equipped with the manual free Easy Tune PID algorithm, which can meet the monitoring and control needs of temperature, current and other parameters in industrial scenarios.
Core functions and features
(1) Functional mode
Provide three core functional versions to adapt to different application scenarios:
Three types of PID controllers: equipped with PID regulation function, supporting Easy Tune, manual tuning, and pre tuning.
Indicator with alarm: only monitors parameters and triggers alarms, without control output.
Pure indicator: only used for parameter display, without alarm and control functions.
(2) Key characteristics
Setpoint Lock: Restricting the operator's permission to modify the controller's set values to avoid erroneous operations affecting system stability.
Flexible output configuration: Supports up to 3 outputs, with a maximum of 1 for control and 2 for alarm. Relays or SSR (Solid State Relay) outputs can be configured according to requirements.
Dual alarm type: supports two types of alarm functions, with alarm triggering conditions including "high process value", "low process value", "set value deviation", and "interval alarm".
Humanized operation interface: adopting a 3-button operation design, paired with a 4-digit 10mm high LED display screen (red/green optional), and equipped with "control", "settings", "alarm", "set value" indicator lights, with clear status visualization.
Sensor disconnection detection: When the sensor (thermocouple, RTD, etc.) is disconnected, it can respond quickly (except for the 0-20mA range, the response time is less than 2 seconds). At this time, the control output is turned off, the thermocouple/mV range triggers a high alarm, and the RTD/mA range triggers a low alarm, improving system safety.
Detailed technical specifications
(1) Input parameters
Input type, specific specifications
Thermocouples support seven types: J, K, R, S, T, B, and N
RTD (Platinum Resistance) 3-wire PT100, with a maximum of 50 Ω per lead (to be balanced)
DC Linear signal supports 0-20mA, 4-20mA, 0-50mV, 10-50mV, with a scalable range (-1999 to 9999), and the decimal point position can be set as needed
Input impedance thermocouple and mV range:>10M Ω; mA range: 4.7 Ω
Accuracy input range ± 0.1% (± 0.25% for J and T-type thermocouples), ± 1 LSD (least significant bit); Thermocouple cold junction compensation (CJC) accuracy better than 0.7 ° C
Sampling rate of 4 times per second, resolution of approximately 14 bits
(2) Output and Communication Options
Control and alarm relays:
Contact type: SPDT (single pole double throw), 2A/240V AC under resistive load; If communication or second relay is configured, all relay contacts will become SPST (single pole single throw).
Lifespan:>500000 operations.
Control SSR output: Drive capability>10V DC, minimum load 500 Ω.
Communication function: Supports 2-wire RS485, baud rate 1200-9600, compatible with Modbus protocol (optional for some models only, specified upon order).
(3) Work and environmental conditions
Temperature: Operating temperature 0-55 ° C, storage temperature -20-80 ° C.
Humidity: 20% -95% RH (non condensing).
Power supply: standard 100-240V AC 50/60Hz (7.5VA); Optional 12-24V AC (7.5VA) or 12-30V DC (4W).
Protection level: front panel IEC IP66, rear panel IP20.
Certification: Complies with CE, UL, and ULc standards.
(4) Physical dimensions
Key dimensions (approximate): 10mm (display height), 45mm ± 0.6 (certain dimension), 49mm, 100mm, 22mm ± 0.3, 25mm (specific installation dimensions need to be based on actual layout reference).
On site reconfiguration and ordering information
(1) On site configurable items
Some functions can be adjusted on-site without the need for additional accessories:
Input type: Can be reconfigured between supported input types (thermocouple, RTD, DC linear signal).
Control/Alarm 1 Output (Controller Version Only): Can be switched to "Relay Control+SSR Alarm 1" or "SSR Control+Relay Alarm 1".
(2) Cannot be configured on-site
It needs to be confirmed at the time of the order and cannot be added or modified later:
Hardware options, such as RS485 communication function and second alarm relay, can only be selected at the time of ordering whether to install them.
(3) Order Code Rules
The ordering code consists of three parts: product model (N2300), output type, display color and power supply, and options. The specific code corresponds to the following:
Output type (second digit)
|Encoding | Output Configuration|
|----|----|
|00 | (not clearly marked, needs to be confirmed based on actual needs)|
|01 | Indicator+Alarm 1 (Relay)|
|02 | Indicator+Alarm 1 (SSR)|
|12 | Controller (relay)+Alarm 1 (SSR)|
