Analog output
Number of programmable analog outputs 1
Terminal number 42
Current range at analog output 0/4–20 mA
Max. load GND - analog output 500 Ω
Accuracy on analog output Max. error: 0.5% of full scale
Resolution on analog output 12 bit
The analog output is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
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
1)
Voltage level at digital/frequency output 0–24 V
Max. output current (sink or source) 40 mA
Max. load at frequency output 1 kΩ
Max. capacitive load at frequency output 10 nF
Minimum output frequency at frequency output 0 Hz
Maximum output frequency at frequency output 32 kHz
Accuracy of frequency output Max. error: 0.1% of full scale
Resolution of frequency outputs 12 bit
1)
Terminal 27 and 29 can also be programmed as input.
The digital output is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
Control card, 24 V DC output
Terminal number 12, 13
Output voltage 24 V +1, -3 V
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.
