Status Output (Option code: /AL)
A unique feature of the EJX-A series is the Status Output option (/AL). This option provides an on/off output signal separate from the 4 to 20 mA analog signal. The on/off output signal is driven off the user-configurable high and low alert values. The status output can be assigned as any combination of the high or low alert values of the Input Pressure, Input Static Pressure, or Capsule Temperature. The status output can be used to drive an audio or visual alarm or even operate a simple on/off valve.
This feature is only available on Yokogawa's EJX-A Series of pressure transmitters.
Uses for the Status Output:
- Tank Level - Eliminates a level switch
- Capsule Temperature - Remote location health monitoring (Adjacent equipment, Heat tracing, or process runaway)
- Static Pressure - Monitor pumps, valves, or tank blankets
- Flow Limits - Alarm at low or high flow conditions
- Diagnostics - Monitor other process conditions without the need or expense of additional devices
The Status Output employs a 5% (5⁰C for temperature) buffer value to avoid output chattering.
Refer to FieldGuide FGP-100 Status Output for additional information.
