Signal Isolator/Repeater AC to DC Signal – ISM-12-1-2 (H)
Signal Isolator/Repeater AC to DC Signal – ISM-12-1-2 (H)
Product Description :
ISM-12-1-2 (H) – Single AC/DC input & two DC output operating on 24VDC (18-36)VDC
- Accepts DC signal inputs and provides optically isolated proportional analogue output.
- On site calibration facility-using ZERO/SPAN presets.
- Operates on 230VAC or 24VDC (18-36) VDC.
- Designed using ultra low drift components for long term stability.
- The interface of low-level signals coming from the sensors or transducers from the plant to DCS, SCADA, PLC or PID process controllers without ground line interferences.
- Signal multiplier – single input and 2 to 4 outputs.
| Parameters | Description |
|---|---|
| Input | 1) DC input - 50mV/75mV/100mV - DC shunt 2) AC input - Current (through external CT) (0-1) A or (0-5) A or Voltage (0-110) VAC or (0-230) VAC or (0-440) VAC 3) High voltage DC from Bridge rectifier or others 200,400,600,700VDC |
| Output | (4-20) mA, (0-5) VDC, (0-10) VDC For current output, RL (max.) = 500 Ohms. For voltage output, RL (min) = 100K Ohms. |
| No. Of Outputs | 1 to 4 parallel independent outputs can be provided for single input. Each output can be same or different. |
| Accuracy | Absolute to the input, Output is proportional to the average vale of AC signal. |
| Calibration | On site calibration facility through ZERO and SPAN presets accessible to the user. |
| Isolation | Input and Output are galvanically/optically isolated for DC inputs and galvanically isolated for the AC inputs. Power supply is also isolated from Input and Output. (3-way isolation). Multiple Outputs are not isolated from each other. |
| Isolation Voltage | Greater than 1 KV. |
| Mounting | 35-mm. DIN rail mounting ABS enclosure. |
| Supply | AC Supply: 230VAC +/-10%, 50/60Hz or DC Supply: 24VDC (18-36)VDC . |
| Size | 22 x75 x 110 |
| Sr. No. | Specifications | Part No. |
