If 4 - 20mA is selected for IN1,let SL specifies the input signal low (i.e. 4mA),
SH specifies the input signal high (i.e. 20mA), S specifies the current input
signal value, the conversion curve of the process value is shown as follows :

O1TY : Selects the signal type for Output 1.
The selection should be consistent with the output 1 module installed.
The available output 1 signal types are :
RELY : Mechanical relay
SSRD : Pulsed voltage output to drive SSR
SSR : Isolated zero-switching solid state relay

The range for linear current or voltage may not be very accurate. For 0% output,
the value for 4 - 20mA may be 3.8mA to 4mA; while for 100% output, the value
for 4 - 20mA may be 20mA to 21mA. However, this deviation will not degrade
the control performance at all.
