Dwyer MPM-141 | Process Panel Meter | 85-265 VAC, 4 Relays, 4-20 mA Output
The Dwyer MPM-141 is a general purpose dual-line process meter with 85-265 VAC power, 4 alarm relays and a 4-20 mA output. Input on the MPM-141 is field-selectable for 0-10 V or 4-20 mA, and it provides 24 VDC to power the transmitter.
- MPM-141 configuration: 85-265 VAC, 4 alarm relays, a 4-20 mA output
- Top line shows the process variable, bottom line the engineering units (MPM-141)
- Dual scale mode on the MPM-141 shows one value in two units, e.g. height and volume
- 32-point linearisation and automated round horizontal tank function in the MPM-141
- MPM-141 front rated NEMA 4X, IP65; dual-line 6-digit display
- MPM-141 relays rated 3 A @ 30 VDC and 125/250 VAC resistive, 0-999.9 s on/off delays
