*1 There are no RTD
input terminals on
the DCV/TC/DI and
Digital input module.
*2 There is no clamp
type terminal for
Digital input module.

Compensation lead
DC current input
Shunt resistor
Note:For 4 to 20mA input, shunt
resistance value should
be 250Ω ±0.1%
10Ω* max./leadwire
Three wire resistances
should be approx. equal.
*10Ω max. for Pt100Ω and
Pt50Ω, 1Ω max. for Cu10Ω.
