Dwyer PPM-141 | Pulse Panel Meter | 85-265 VAC, 4 relays, 4-20 mA Transmitter
Dwyer PPM-141 is an 85-265 VAC pulse panel meter supplied with four relays and a 4-20 mA transmitter output. The PPM-141 accepts a pulse input, powers the flowmeter with 5, 10 or 24 VDC, and sends 4-20 mA over long distances to a PLC.
- PPM-141 supply: 85-265 VAC (85 to 265 VAC 50/60 Hz or 90 to 265 VDC, 20 W max)
- Four relays on the PPM-141, rated 3 A at 30 VDC and 125/250 VAC resistive, with independent 0 to 999.9 s delays
- Dual-line 6-digit display (0.60 in and 0.46 in) with five user-selectable decimal positions on the PPM-141
- NEMA 4X, IP65 front with accuracy of +/-0.03% of calibrated span +/-1 count (PPM-141)
- Free USB programming software resident on the meter; CE, RoHS, UL and cUL approvals (PPM-141)
