JH1005: Single Trip Alarm
JH1025: Dual Trip Alarm
Models JH1005 and JH1025 provide 24Vdc loop excitation for a remote 2-wire transmitter, take the signal from that transmitter and provide relay contact HI/LO trip outputs. They also may be used with DC-powered "3-wire" sensors and transmitters whose supply currents do not exceed 25mA.
The alarm trip points are adjustable anywhere within the input range. Deadbands also are fully adjustable, from 0.25% to 100% of span. A slide switch, accessible through the top of the enclosure, selects HI or LO trip operation (on dual alarms, HI/HI, HI/LO or LO/LO). Red/green LEDs indicate alarm status.
Alarm contacts are rated at 5 amps, 230Vac or 30Vdc. Model JH1005 provides one set of DPDT relay contacts; Model JH1025, two SPDT relays. AC and DC power options are available.
