Input resistance, R
i
approx. 4 kΩ
All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
*) Terminals 27 and 29 can also be programmed as output.
Control card, RS-485 serial communication
Terminal number 68 (P, TX+, RX+), 69 (N, TX-, RX-)
Terminal number 61 Common for terminals 68 and 69
The RS-485 serial communication circuit is functionally separated from other central circuits and galvanically isolated from the
supply voltage (PELV).
Digital output
Programmable digital/pulse outputs 2
Terminal number 27, 29

Voltage level at digital/frequency output 0–24 V
Max. output current (sink or source) 40 mA
1) Terminal 27 and 29 can also be programmed as input.
Control card, 24 V DC output
Terminal number 13
Max. load 200 mA
The 24 V DC supply is galvanically isolated from the supply voltage (PELV), but has the same potential as the analog and digital
inputs and outputs.
