Product Overview
The Aplisens PMT-920 Digital Indicator with Relay Outputs is typically selected by sensor type (Pt100/Pt500/Pt1000), alarm/relay needs, and panel cut-out requirements. For accurate selection and pricing, please call 865-900-8844 or email KSmith@CPSCalibrations.com.
The Aplisens PMT-920 is a programmable digital temperature indicator designed to work with resistance temperature sensors Pt100, Pt500, and Pt1000. It supports 2-, 3-, or 4-wire sensor connections and automatically compensates line resistance for 3- and 4-wire sensors. Two independent alarm setpoints can control the two relay outputs, with front-panel indication when alarms are active.
- Sensor inputs: Pt100 / Pt500 / Pt1000
- Alarm control: 2 settable relay outputs (R1 / R2)
- Wiring: 2-, 3-, or 4-wire (auto compensation on 3/4-wire)
- Programmable: relay level & hysteresis, alarm contact state, password, display filtering, display color (green/red)

PMT-920 selection is straightforward. To quote and configure correctly, we typically confirm:
| What We Need | Examples |
|---|---|
| Sensor type | Pt100, Pt500, or Pt1000 |
| Wiring method | 2-wire, 3-wire, or 4-wire |
| Alarm logic | Alarm setpoints, hysteresis, and whether relay contact is NO/NC during alarm |
| Display preferences | Filter level and display color (green or red) |
| Power & panel fit | 85–260 VAC/DC supply and 67 × 32.5 mm cut-out confirmation |
Ordering format: PMT-920 / (input selection). If you tell us your sensor type and wiring, we can help confirm the best setup.
