IECEx Explosion Proof Indicator
for 4 to 20mA input
The P27D is a loop powered, digital, IECEx explosion proof indicator, approved to Ex d IIC T6 Gb (Gas) and Ex tb IIIC Db (Dust) for zone 1 use. It allows a process variable from any 4 to 20mA current source to be monitored. Since the unit derives its power from the loop, no additional power supply or wiring is needed. A low voltage drop (5 Volts at 20mA) means it can be incorporated into almost any 2 wire loop where local or remote indication is needed. The P27D has a 4 digit display which can be configured to read from -999 to 9999 with a 4 to 20mA input signal. The decimal point location and engineering units are adjusted using membrane switches and the indicator can be mounted directly to our thermocouple & RTD sensors or alternatively wall/pipe mounted using the mounting brackets shown below.
- Approved to Ex II 2 GD Ex d IIC Gb (Gas) and Ex tb IIIC Db (Dust)
- IP68 die cast alloy enclosure as standard, 316SS version available on request
- For local or remote indication of 4~20mA signal. Direct sensor or wall/pipe mounting options available.
- Can accommodate a head mount 4~20mA transmitter if required
