2.3.2.4 Signal connection for TTL counter expansion

Without any option the counter or digital inputs are wired to a 68 pin female connector on DEWETRON

instruments. An easy sensor connection possibility is given with ORION-CB-CNT8 connection box.

For direct connection of the sensor to the instrument various options for counter panels are available:

ORION-DIO-PANEL-1

These panels should be used if mainly counter/encoder signals will be measured. All eight counters are

wired to 7-pin Lemo connectors and Ex_DI 0 to Ex_DI 15 are connected to a DB37.

ORION-DIO-PANEL-2

All 32 digital inputs are wired to two DB37 connectors. Ex_CNT 0 and Ex_CNT 1 are connected to a 7-pin

Lemo. Therefore this panel is suitable if mainly standard digital inputs are requested.

ORION-DIO-PANEL-3

This option is similar to Panel-2 except the digital inputs are galvanically isolated. The two counter inputs are

not isolated.

Non isolated DB37 pinout for ORION-DIO-PANEL-1 and ORION-DIO-PANEL-2:
