The 0-200mV input range ideal for use with DC shunts. A fully isolated 4-20mA retransmission is provided for each input with zero and span adjustment being provided for all channels.

One, two, three or four channel models are available in the same compact (only 44mm wide) case. A LED for each channel gives output level indication by varying its brightness with the output current.

An optional 240VAC or 110VAC supply is available for one or two channel models. This option provides two isolated 24VDC supplies.
