9203B Type - EX Solenoid / Alarm Driver

PR Electronics 9203B Universal Ex driver for solenoids, acoustic alarms and LEDs. Used anywhere intrinsically safe levels of energy need to be sent to devices located in a flammable atmosphere. The PR 9203B uses transformer and optical isolation techniques to provide 2.6 kV galvanic isolation between the input, output and power terminals. The high level of electrical isolation means that input pulses sensed at the 9203B are not electrically connected to the output pulse. The 9203B has been designed, developed and certified for use in SIL 2 applications according to the requirements of IEC 61508.

Features and Benefits

• Can be mounted in the safe area or in zone 2 / div. 2 and transmit signals to zone 0, 1, 2 and zone 20, 21, 22 including M1 mining / Class I/II/III, Div. 1, Gr. A-G.
• Configuration and monitoring by way of detachable display front (PR 4501)
• 2.6 kVac galvanic isolation between input, output and supply
• Selection of direct or inverted function for each channel via PR 4501
• Monitoring of internal error events via the individual status relay and/or a collective electronic signal
• Designed, developed and certified for use in SIL 2 applications
• Front LED indicates operation status and malfunction
• Can be supplied separately or installed on power rail, PR type 9400
• DIN rail mounting

Programming

The 9203B universal transmitters are programmable via the PR 4501 detachable display module (7966890). The 4501 module allows the programming of the vast array of input and output parameters easily and safely. Together with advanced functions including 2 point calibration, process simulation and diagnostics.
With a simple menu and explanatory text the 4501 is extremely straightforward to navigate. Functions are clearly depicted on the 4 line LCD display even in low light conditions. Line 1 shows the input signal, line 2 shows the units, and line 3 shows analogue output or tag number. Line 4 shows the communication and relay status. In addition the 4501 features password protection. Programming access can be blocked by assigning a password which is conveniently saved in the 9203B transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.
