Signal Isolation Module
SIM200-000

D.C. Power Input

• 24 VDC ±10%, 400mA max.

 Isolation Voltage

• 500V (DC or AC Peak)

 Linearity

• ±0.5% of 10 VDC span

 Signal Inputs

• Pot Input

+15 VDC, ±5% available to source a 2000 to 10,000 Ohm pot. Use 25 VDC Input Range with external pot.

• Voltage Input

4 selectable ranges  (via J1) with greater than 1 meg Ohm input impedance.

• Current Input

Single input range (max ±20mA) with 250 ohm impedance.  Maximum output is ±12VDC or ±24mA.

• Trim Potentiometer Input

Allows connection of an external 10,000 Ohm pot. to trim the output. Trim range may be as wide as 0 to 100% or limited to 80 to 100%.

Signal Outputs

• Voltage Output

Selected by position V on J2. This circuit allows the output to source a voltage level of up to ±12 VDC into a minimum resistance of 600 Ohms. If resistance is too low, output linearity may be affected.

• Current Output

Selected by position I on J2.  This circuit allows the output to source a regulated current of up to ±20mA into a maximum resistance of 500 Ohms. Using the BIAS pot, the output can source a 4 to 20mA signal.

Temperature Range

• Chassis: 0-55ºC
