YASKAWA 120 Series I/O Modules

YASKAWA 120 Series I/O Modules

The user manual for YASKAWA 120 series I/O modules (compatible with MEMOCON GL120, GL130 PLC) covers the specifications, installation wiring, I/O allocation, MEMOSOFT operation and maintenance of three types of modules: digital I/O, analog I/O, and register I/O. It specifies the voltage range of the module (such as digital input 100/200VAC, 12/24VDC, analog output ± 10V/4-20mA), point configuration (16/32/64 points, etc.), wiring specifications, I/O address allocation rules, and safety operation requirements (such as grounding resistance ≤ 100 Ω, hot plug support), and is responsible for module installation, debugging, and maintenance.

Installation and wiring specifications

Environmental Requirements

Working temperature: 0~60 ℃, storage temperature: -25~85 ℃

Humidity: 30%~95% (no condensation), no corrosive gases

Vibration: 10-57Hz (0.075mm half amplitude), 57-150Hz (9.8m/s ² acceleration)

Installation operation

Module fixation: M4 screws are tightened, and adjacent modules are reserved with heat dissipation spacing

Terminal block installation: AC module needs to be powered off to avoid electric shock

Hot swappable: Supports live plugging (AC modules require safety switches)

Wiring requirements

Cable selection: shielded twisted pair (signal), independent wiring (power)

Distance requirement: The distance between power lines and signal lines should be ≥ 200mm, and cables of different voltage levels should be slotted

Grounding specification: Single point grounding of shielding layer, grounding resistance ≤ 100 Ω

Surge protection: parallel surge absorbers (AC) or freewheeling diodes (DC) for inductive loads

I/O allocation rules

Digital I/O Address Allocation

Input relay: CPU 10/20/21 range 100001-101024, CPU 30/35 range 100001-104096

Output coil: CPU 10/20/21 range 00000 1-001024, CPU 30/35 range 00000 1-004096

Address step size: 16 point module step size of 16 (e.g. starting from 100001 for 16 point input, next 100017)

Simulate I/O address allocation

Input registers: 300001-300512 (5 registers per module)

Output registers: 400001-400512 (2 registers per module)

Register I/O address allocation

Input registers: 300001-300512 (1-16 registers optional)

Output registers: 400001-400512 (1-16 registers optional)

MEMOSOFT operation

Configuration requirements: Supports MEMOSOFT version ≥ 1.21 (DOS) for 64 point modules, corresponding CPU version (such as CPU 10 ≥ 00A01)

Core operations: Module type setting (input the last 11 digits of the model), I/O address starting value configuration, data format (BIN/BCD), bit sequence (MSB/LSB)

Special settings: Simulation module software filtering (no filtering/3-time average/5-time average), register module read/write cycle (8CH minimum 32ms)

Maintenance and troubleshooting

Maintenance points

Fuse replacement: Authorized personnel only, specifications match (such as DC8 point module 3.5A fuse)

Insulation testing: Regularly use a 500VDC megohmmeter to test, with insulation resistance ≥ 100M Ω

Battery maintenance: The lithium battery (3.6V) of the register module has a lifespan of about 10 years and needs to be replaced if the voltage is ≤ 2.8V

Common Faults

Over range: ERR indicator light is on, check the input/output signal range (such as analog input ± 10V exceeding ± 10.24V)

Power supply abnormality: The P.OK light is not on. Check the polarity and voltage range of the ± 12V/+5V power supply

Communication failure: The ACTION light is not on. Please verify that the I/O allocation matches the module model
