Industrial Digital Gauges with High/Low and High/High-High Alarms
Switch
BPK-IV Pressure Gauge/Switch
Introduction:
The BPK-IV series controllers have display, control and
transmission functions and have been used in many automatic control
fields. Their main features are as follows:
1. Various RTDS, thermocouples or standard input signals can be
selected (see table). The display range can be calibrated for
nonlinear signals or set for linear signals.
2. Isolated transmission output is 12 bit resolution. Its scope can
be set.
3. Two relay outputs, can be set high/low, high/high-high or
low/low-low alarm action type.
Specification
1. Supply voltage:220VAC /24VDC(±10%);
2. Ambient temperature:0~50ºC; relative humidity:≤85%Non corrosive

This product is only manufactured into 4 ~ 20mA or 0 ~ 20mA output
current signals. If the user needs the voltage output signal
transmission output, it can be customized from the manufacturer or
self-connected 250 or 500 ohm resistance for 1 ~ 5V or 0 ~ 5V, 0 ~
10V voltage and resistance (note: the accuracy of the resistance
directly affects the accuracy of the transmission output voltage).
