Signal Isolator Remote I O Module Digital Input Switch Input Dry
Contact Output 2ch
Input
Input signal: switch, proximity switch, frequency ≤ 10Hz
Distribution voltage: ≈8V (when open)
Short circuit current: ≈8mA
Output
Relay output
Characteristics:
Response time: ≤20mS
Drive capacity: 2A/250V AC; 2A/30V DC
Load type: resistive load
Input and output characteristics (when set to in-phase control):
The field switch is closed or the input loop current is >2.1mA,
the output relay is closed, and the CH channel indicator is yellow.
Field switch open circuit or input loop current <1.2mA output
relay open circuit, CH channel indicator light does not light.
Switch setting
Note: When the switch input needs to be disconnected, it needs to
be connected in parallel at both ends of the switch; 10KΩ resistor
(such as switch || in the right wiring diagram)
Basic parameters
Power: DC24V Voltage range: DC20-40V
Current consumption: ≤50mA (one input and one output, 24V power
supply, when the relay contacts are closed); ≤60mA (one input and
two output, two input and two output, 24V power supply, when the
relay contacts are closed)
Insulation strength: 1500V AC / 1min (between input, output, and
power)
Insulation resistance: ≥100Ω (between input, output, and power)
Operating temperature range: -20~ +55 degrees
Electromagnetic compatibility: in accordance with GB/T 18268
(IEC61326-1)
Applicable field devices:
In line with DIN 19234 NAMUR proximity switches, switches and other
field devices (including intrinsically safe pressure switches,
temperature switches, liquid level switches, etc.)
