20ALMDC-AXXX-8

Y E A R G U Loop Powered Trip Amplifiers 20ALM The 20ALM is an input loop powered trip amplifier, deriving its power from the input signal High or low alarm option Low voltage drop Setpoints available on front panel as 0.4 to 2V signal (4 to 20mA) LED indication of alarm Unique low cost solution Options and ordering codes Description The output of the 20ALM is a single pole, normally open, solid state relay 20ALM - 115VAC - AXXX - 8 which can be configured to close either above or below the adjustable setpoint. The switched output can be connected to any potential within 1kV of the transmitter supply, while transients of 2.5kV can be withstood. Options The relay is designed to switch AC or DC. 115VAC rated contacts 115VAC The trip amplifier is typically used to activate a warning or control system 24VAC/DC rated contacts DC override when a sensor output goes above or below a pre-set limit. Alternatively, the unit can be used for simple on/off control, having a built in switching hysteresis. Dimensions (mm) The device is housed in an ultra-compact DIN-Rail mounted enclosure, only 63mm 18mm wide.

Setpoint can be checked by measuring the 0.4 to 2V (4 to 20mA) voltage on the front panel terminals. High or low alarm is selectable using internal link. Closed output contact is indicated by a red LED on the front panel. 20ALM/03/03 www.imopc.com A R A N T E E 18mm 58mmX-ON Electronics Largest Supplier of Electrical and Electronic Components Click to view similar products for imo manufacturer: Other Similar products are found below : 20.155MV/12-E MC14N-S-10110AC MB09-S-10=24 DPS-1-030-24 SRF-1C-SL-12VDC MB09-S-1024 LDC18RRS SFSYE0111 21.1500M/6-E 20.3304M/2-E 21.910M/5-E 20.95MA/2-E 21.95MHF/2-E PE69-4032 DPS-1-060-24 CS20A-A2 CS20A-U1 VFC02 MSSTC11DA06 20.95MHF/3-E B3T10 XKL-040-21 20.3304M/4-E SRDH-1A-SL-24VDC 20.2500M/5-E 21.155MH/12 SRRHN-2CN- SL-12VDC 20.920M/5-E MC10N-S-10110AC 21.1550MF/8-E 20.910M/6-E 20.95MH/3-E 21.95MV/3 MA05-S-01230AC SRRHN-2CN- SL-5VDC LB69-4040 20.3001M/6 21.1500M/3-E SFSYE0311 21.95MHF/6-E 20.95MV/2-E 20.155MV/4-E 20.155MH/4-E 20.950M/2-E MT5 1-50-FAR BS3P3REDO MB12-S-10=24 MA05-S-1024DC 20.155MVF/8-E 20.2500MV/8-E
