Relay Module 4/8 Ch

Output module in 2 versions with 4 or 8 independent relay outputs for switching
24 V DC and 240 V AC mains power loads.
112

communication are also supported.
Typically 24 V, depending on the supply voltage of the
Docking Station
Max. 500 mA per channel
Total transmitter supply current per module:
2 Ports max. 1 A
4 Ports max. 2 A
If 1 A or 2 A is exceeded, the transmitters require an
external power supply.
At ambient temperatures <50 °C, the max. transmitter
supply current per module is 2 A.
262 ohm
± 0.05 mA ±0.002 mA/K [0 ... 4 mA]
± 1.25 % ±0.05%/K [4 ... 24 mA]
Max. 2.1 A
Max. 5 W at 24 V
1 s
– wire break detection (loop current < 0.1 mA)
– Fault detection (loop current > 38 mA; this value
should be included when calculating the maximum
line resistances)
– Short circuit detection (transmitter supply current >
500 mA; channel shuts down if this is exceeded)
– Total current monitoring (sum of transmitter supply
currents on all channels > 2,000 mA; module shuts
down if this is exceeded)
