3.2 Onboard I/O (Enhanced)

Input:

6-way digital input (4+2 interrupt), same as M2xxx

2-channel universal analog input (terminal X1): -10...+10 V, 0... ± 20 mA, Pt1000, Ni1000 L&S, 0... 2.5 k Ω, 12 bits

4-channel dedicated analog input (EA 1 slot): 0... 10 V, 0 (4)... 20 mA, Pt1000, Pt500, Ni1000, 14 bit resolution

output:

4-channel digital output (24 VDC/0.5 A)

1 PWM output (24 VDC/0.2 A)

2-channel analog output (EA 1 slot): 0... 10 V or 0 (4)... 20 mA, 12 bits, configurable through PG5

Configurable (via PG5):

4-channel digital input/output (terminal X0)

Watchdog relay (terminal X3)

3.3 Expansion Limitations and Special Instructions

Only supports one I/O slot (I/O 0): can be inserted into a PCD2.M5 I/O module or a PCD2.F2xxx communication module (up to 1 F2xxx module).

Slot I/O 1 pre installed with PCD2.W525 module: This module is part of the default configuration of the controller, and if removed, the controller will stop running. Therefore, users are not allowed to freely expand using the I/O 1 slot.

The Smart RIO Manager feature is not supported.

Supports S-Bus and Modbus stations, with a maximum of 10 units.

3.4 Communication Expansion and Memory Expansion (Same as M2xxx Series)

Slot A: PDC7.F1xxx Communication Expansion

Slot M1: PCD7.Rxxx flash module, can activate BACnet IP or LON IP

Slot I/O 0: Optional PCD2.F2150 (BACnet MS/TP), PCD2.F2400 (LON FTT10), etc

3.5 Typical Applications

Radiators, fan coil units, cooling ceilings, VAV (Variable Air Volume) control

Air quality monitoring

Signal contacts (occupancy control, presence detection, window monitoring)

Lighting control, sunshade control

Connect external devices through analog signals, S-Bus, Modbus, BACnet, LON, KNX IP, EnOcean, etc

PCD1 E-Controller (M0160E0): Energy Monitoring Controller for Distribution Box

PCD1.M0160E0 is a compact controller with free programming, pre installed with S-Monitoring application (energy monitoring) at the factory. It is designed specifically for the installation of electrical control cabinets, suitable for distribution units or narrow spaces. In addition to integrating I/O, interface, and Web/IT functions, it also supports multiple protocol connections, making it highly suitable for microcontrollers, communication gateways (EnOcean, KNX, BACnet, etc.), as well as energy consumption data collection, recording, and processing.

4.1 Technical specifications

Program memory: 1 MB Flash

Working memory: 1 MB RAM

File System: 128 MB

Integrated communication: Ethernet (dual port switch), USB, RS-485 (as before)

Automated Server: Supports

Dimensions (W × H × D): 142 × 142 × 60 mm (excluding terminals)

Installation method: Single 35mm top cap rail (DIN EN60715 TH35) or flat installation

4.2 Onboard I/O

Input:

6-way digital input (4+2 interrupt), 15... 30 VDC

2-channel analog input (terminal X1): -10...+10 V, 0... ± 20 mA, Pt1000, Ni1000, Ni1000 L&S, 0... 2.5 k Ω, 12 bits. The default factory configuration is Ni1000 sensor input.

output:

4-channel digital output (24 VDC)

1 PWM output (24 VDC/0.2 A)

Configurable (via PG5):

4-channel digital input or output (terminal X0), factory default configuration is digital input

Note: This model does not have a free I/O slot (no EA slot), only one slot A is used for communication expansion.

4.3 Special Installation Requirements

When installed in the distribution box, a space of 55mm should be left above the DIN rail and 75mm below it.

It is recommended to use elbows or flexible Ethernet cables (such as SlimWire PRO) for Ethernet cables, otherwise it may not be possible to close the distribution box cover.
