特性

• Universal I.S. driver for the control of solenoids etc. with various I.S. data by way of three built-in I.S. barriers.
• Two hardware versions make it possible to choose either Low (35 mA) or High (60 mA) current output.
• Configuration and monitoring by way of detachable display front (PR 4501).
• Selection of direct or inverted function for each channel via PR 4501 and the possibility of reducing the output current to the hazardous area to suit the application.
• Optional monitoring of the output current to the hazardous area by way of PR 4501.
• Optional redundant supply via power rail and/or separate supply.
• 9203B can be mounted in the safe area or in zone 2 / div. 2 and receive signals from zone 0, 1, 2 and zone 20, 21, 22 including mining / Class I/II/III, Div. 1, Gr. A-G.
• I.S. driver for the control of ON / OFF solenoids, acoustic alarms and LEDs mounted in the hazardous area.
• The 9203B is controlled by an NPN/PNP signal or a switch signal.
• Monitoring of internal error events via the individual status relay and/or a collective electronic signal via the power rail.
• The 9203B has been designed, developed and certified for use in SIL 2 applications according to the requirements of IEC 61508.
• 1 green and 2 yellow/red front LEDs indicate operation status and malfunction.
• 2.6 kVAC galvanic isolation between input, output and supply.
• The devices can be mounted vertically or horizontally without distance between neighbouring units.
