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
4 - 20 : 4 - 20 mA linear current output
0 - 20 : 0 - 20 mA linear current output
0 - 1 V : 0 - 1 V linear voltage output
0 - 5 V : 0 - 5 V linear voltage output
1 - 5 V : 1 - 5 V linear voltage output
0 - 10V : 0 - 10 V linear voltage output

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