INSTRUMENT DESCRIPTION
2.1
DESCRIPTION
OM 402PID is a 4-digit versatile panel mount PID regulator designed for maximum fl exibility and user comfort while maintaining
a low price.
Type OM 402PID is a multifunction instrument with the option of confi guration for 8 various input options, easily confi gurable in
the instrument menu. In its basic confi guration the OM 402PID has two regulatory relays and two relay alarm outputs. Desired
value can either be constant, or defi ned by one of 14 programmes.
The instrument is based on a 8-bit microcontroller and a multichannel 24-bit sigma-delta converter, which secures high accuracy,
stability and easy operation of the instrument.

Launching:
time - one off /weekly, by external input, by buttons
RELAY OUTPUTS
Type:
digital, settable in the menu
Outputs:
relays L1, L2 are alarm outputs, relays L3, L4 are intended as regulatory but can be also used as alarms
ANALOG OUTPUT
Usage:
where this type of signal is requested by action devices, or it can be used for processing of the measured
value by external devices.
Type:
electrically isolated, programmable with a 12 bit D/A convertor. Functions, type and range of the output
are seelctable in the instrument‘s menu
COMPENSATION
of conduct:
in the menu it is possible to perform compensation for 2-wire connection
of conduct in probe:
internal connection (conduct resistance in measuring head)
of CJC (T/C):
manual or automatic, in the menu it is possible to perform selection of the type of thermocouple and
compensation of cold junctions, which is adjustable or automatic(temperature at the brackets)
* only for types DC, PM, DU
