RTU-710T
Radio Slave Station TETRA
On-off inputs:
The module's 16 opto-isolated on-off inputs can be connected in groups of 4 for +ve or -ve polarity. Each input is assigned a 16-bit counter that can be used as a time totalizer or event counter at up to 10 pulses/sec, if and as required.
On-off outputs:
The on-off outputs are opto-isolated PNP transistors (+ve switching) rated for loads up to 500 mA, 12-24 VDC.
Analog inputs:
These inputs accept 0-20 mA or 4-20 mA sensor/transmitter signals that are digitized with 12-bit resolution.
I/O Expansion:
RTU-710T modules have an I/O expansion bus interface through which Type PEM I/O Expansion Modules can be connected, to increase the I/Os available. Every time the RTU module is started up, it automatically scans this bus interface to check what Expansion Modules are connected, and their I/O configurations.
