2. PLC11-01 HARDWARE FEATURES

The PLC11-01 accessory has the following hardware features:
- 9 isolated and bi-directional digital inputs, two of them are fast and may generate
interrupts.
- 3 relay digital outputs 250 V @ 3 A;
- 3 opto-isolated and bi-directional digital outputs 24 V @ 500 mA;
- 1 differential analog input (-10 to +10 VDC or 0 to +20 mA) with 14-bits reso-
lution;
- 2 analog outputs (-10 to +10 VDC or 0 to 20 mA) with 12-bits resolution;
- 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.
