Table 8. RTI-12306 MDR Pinout Signal Descriptions
Signal Description
CurrentCh[n]+ Voltage proportional to current on Channel_n, plus common mode voltage.
The full scale range is ±2 +2.5 V.
CurrentCh[n]– Common mode voltage of Channel_n (2.5 V).
GND Ground reference for all signals.
Terminal Blocks
The following terminal blocks connect to the LOAD connectors on the SLSC-12251/12252
through SPxM-SPxF cables and provide easy spring terminal connections to the LOAD
channels. The low voltage (<33 V) terminal block options also provide an HD44 connection
for routing low current sense LOAD signals to an SLSC-12201 module.
On all terminal blocks, terminal J5 can be used for Chassis Ground, which is tied to the metal
case standoffs and connector jack-sockets. Terminal J6 is DGND, which is the GND reference
of the signals on the HD44 connector.
TB-12396
The TB-12396 is a terminal block for use with SLSC-12251 devices.
