2. PLC11 - 02 HARDWARE FEATURES

The PLC11 - 02 accessory has the following hardware features:
- 4 isolated and bi-directional digital inputs, two of them are fast and may generate
interrupts.
- 1 relay digital output 250 V @ 3 A;
- 3 opto-isolated and bi-directional digital outputs 24 V @ 500 mA;
- 2 isolated encoder inputs, with internal power supply (5 VDC or 12 VDC);
- 1 RS-485 serial communication interface (Standard protocol: MODBUS-RTU);
- 1 CAN interface.
