Key Features
Two 0–10 V analog inputs and one 0–10 V analog output; 12-bit nominal range 0–4095
User program with an FX3U-style device and instruction model; confirm GX Works2 setup for the supplied hardware
Relay outputs by default; NPN transistor outputs are a separate DC option
Real-time clock is standard; verify clock backup and recovery for the delivered unit
Up to two RS485 ports as an option; Modbus RTU master/slave or non-protocol RS communication
Specifications
Digital Inputs
- Channels
- 14
- Connection
- S/S to +24 V; dry contact or compatible sinking signal to 0 V; verify input thresholds and limits
Digital Outputs
- Channels
- 14
- Hardware
- Relay (default) or NPN transistor (optional); verify the ordered hardware
- Relay
- Stated ceiling 5 A at AC 220 V or DC 30 V; load and common-terminal limits must be confirmed
- Npn
- Stated ceiling 3 A, DC only; confirm voltage, load and common-terminal ratings
Analog I/O
- Channels
- 2 AI + 1 AO
- Signal
- 0–10 V; nominal raw range 0–4095, 12-bit resolution
- Terminals
- AD0, AD1, DA0, GND; confirm input, output and reference limits
Control And Communication
- Programming
- GX Works2 with FX3U-style device model; verify software and transfer settings
- Rtc
- Standard; verify backup and recovery
- Rs485
- Optional, up to two fitted ports; specify when ordering; RS and ADPRW cannot operate simultaneously
Power And Mechanical
- Supply
- 24 VDC nominal; obtain supply range, consumption and inrush
- Enclosure
- 150 × 99 × 41 mm (width × height × depth); 14-channel NPN enclosure dimensions require confirmation
Application Limits
- Safety
- Not a safety PLC or sole protective control; independent safety functions may be required
- High Speed
- Specify counting and pulse requirements; suitable hardware and channel ratings must be confirmed
- Startup
- Test startup, STOP, power loss and communication recovery with loads isolated
