2 Channels Digital Signal Isolator Modbus I/O Module Dry Contact Output CE Approval

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.)
