1 GENERAL DESCRIPTION
The four channel analogue receiver is part of a family of explosion protected DIN rail
mounting modules that transmit to and receive from an Austdac SILBUS field bus network.
The SILBUS-RX4A can receive up to four analogue signals on four independent valid
SILBUS channels.
The four analogue outputs are galvanically isolated from the SILBUS network port. This
isolation allows the SILBUS-RX4A to provide many simple and highly effective solutions
when used in installations involving intrinsically safe and non-intrinsically safe circuits.
The receiver is housed within a DIN rail mounting enclosure measuring 100mm (W) x
75mm (H) x 110mm (D). The front panel is located between the two top of enclosure
mounted terminal blocks to provide a clear view of the operation indicating LED’s. Two
LED’s are provided to show power and SILBUS network status.
The SILBUS-RX4A can be quickly and simply configured using a laptop computer running
Hyper Terminal and a small plug in programming adaptor. Each analogue output can be
independently programmed to any SILBUS channel address. Each analogue output can
also have it’s under range, hysteresis, digital fault channels and transmission protocol
configured by the user.
2 FRONT PANEL LAYOUT
The four channel analogue receiver front panel is located between the terminal blocks that
form part of the enclosure. The front panel is shown in photograph 1 below.
