Page 5: General Description
The four channel analogue transmitter 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-TX4A(G) can transmit up to four 4-20mA or 0.4-2.0V analogue signals on four independent valid SILBUS channels. -
Page 6: User Access
EARTH 2.1 USER ACCESS There are no user serviceable parts within the SILBUS-TX4A(G). The user should not open or disassemble the SILBUS-TX4A(G). 2.2 STORAGE, INSTALLATION, USE AND MAINTAINANCE REQUIREMENTS The SILBUS-TX4A(G) should only be installed, operated and maintained by qualified personnel in accordance with the condition of safe use as outlined in the certificate. -

(Fastlink) or eight bit (Analink) value ready for transmission on the configured SILBUS channel. The transmission protocol can be independently selected for each analogue input. See Austdac document 120-009-10 for a more detailed description of SILBUS communications. -
Page 9: Operating Instructions
fault is generated. This fault can be transmitted as a digital signal on any valid configurable SILBUS channel address. Each analogue input is also compared with up to five configurable rising or falling set points. If the analogue input signal passes a set point level a digital alarm will be generated. This alarm can be configured to transmit on any valid SILBUS channel address. -
Page 10: Configuration
To use the console port an Austdac MEAN1 interface, A to B USB cable and laptop computer running Hyper Terminal are required. -

Page 22: Upload Configuration Command
The following table may be used to record the configuration of the SILBUS-TX4A four channel analogue transmitter. 6.18 UPLOAD CONFIGURATION COMMAND The upload configuration command is used to extract the configuration profile of the SILBUS-TX4A via the MEAN1 interface and record it in a file on a PC. Having an exact copy of the configuration is useful for record keeping and future cloning of new SILBUS- TX4A transmitters for maintenance or system expansion. -

Page 26: Power Input Port
When a link is placed between the ‘HI’ and ‘I to V’ terminals of an input it is converted to a current type input with a 100Ω current to voltage conversion resistor across the input. This resistor will convert 4-20mA signals to 0.4-2.0V signals at the ‘HI’ and ‘LO’ terminals. The analogue inputs are galvanically isolated from the SILBUS network port;... -
Page 27: Silbus-Tx4Ag Variant
The analogue input terminals are separated from all other terminals by more than 50mm. The individual analogue input channels are separated from each other by more than 6mm. This certification allows the four channel analogue transmitter to be located wholly within the hazardous area and the connection of intrinsically safe circuits to its various ports. -
