Relay output module 4x NO contact
Relay output module for the PM-50 base unit
Relay output module for the PM-50 base unit
- 4x relay with NO contact
- 3 A at 250 VAC or 30 VDC; resistive load
- Removable terminal strip

The relay output module expands the PM-50 graphic display quickly and easily with additional switching outputs (4x NO contacts).
Outputs:
4 x NO contact
Details:
Type: Form A relay
Switching capacity: 3 A at 250 VAC or 30 VDC; resistive load
When all relays are active, the maximum current is 1A per relay.
The 4 NO relays are divided into 2 relay groups:
Relay group 1 = relay 1 and relay 2, with common ground
Relay group 2 = relay 3 and relay 4, with common earth
Insulation: 3000 Vrms for 1 min.
Note:
If the relay contacts are connected to the mains supply, the mains supply must be overvoltage category II, polarity reversal degree 2.
Life expectancy:
At least 100,000 cycles at full load.
An external protective circuit using RC elements extends the service life of the relays.
Connections:
Spring clamp up to 16 AWG (1.31 mm²)
Length of wire section: 8 mm to 9 mm (0.32" to 0.35")
Power supply:
Via the PM-50 base module
Maximum power 0.9 W
Weight:
51,0 g
Operating temperature:
-10 °C to + 55°C
Relative humidity:
0 % to 85 %, non-condensing
Protection class:
IP25
Dimensions (WxHxD):
44.8 mm x 44.8 mm x 34.1 mm
Note:
Each expansion module (RS232, Ethernet, analog output, relay, AC power supply) can only be plugged in / installed once.
