The EL037 has 4 input channels when used with the EL005 logger (3 channels are available when used with the EL008), each channel can be be configured independently (using jumpers) to measure ±2.5 V, ±10 V or 4–20 mA. It can also route an external power supply (perhaps 12 V or 24 V, depending on the requirements of the input devices) to each of the input devices. Connections to the input channels are via screw terminals.
|±2.5 V||-16 bits + sign||±0.2%|
|±10 V||-16 bits + sign||±0.4%|
|4-20mA||-16 bits + sign||±0.3%|
