used.
Inputs Differential, can use grounded and isolated probes
Common mode voltage range -2V to +3V
Analog Input Channels
Analog Input Channels 4 Channels with dipswitch programmable 1k pullup resistor
Pressure Sender Input
Pressure Sensors
Resistive Senders: The EMS-3 supports resistive type pressure
senders.
VDO Resistive Senders: The EMS-3 supports the VDO 2, 5 and 10
Bar senders. VDO pressure senders used to measure fuel pressure require
the fuel isolation kit available from VDO.
4-20mA Senders: The EMS-3 supports 4-20mA current output
pressure senders.
Voltage Output Pressure Senders: The EMS-3 supports voltage
output pressure senders.
SENDO Voltage Output Pressure Senders: The EMS-3
supports the SENDO MPS 2, 5, 7, and 10 bar senders.
