If more than the maximum 16 supported Modbus Server Connections are attempted, the TCP connection may succeed, but no data may be subsequently transferred.Rising, falling, STEL and LTEL / RATE alarm outputs. * Update alarm on individual or multi channel alarms. * Remote inhibit and reset inputs. * Time delay on switch on and/or switch off of relay outputs. * Optional 0 - 20mA or 4 - 20mA isolated monitor output. * Easy to calibrate and operate using a dedicated Engineering card. * EMC compliant. * Options provided via Engineering Card: * Master Alarm Update. * Event Printers. * Serial communication using Modbus protocol.The system consists of individual 1'' (2.54cm) wide cards fitted to a rigid custom rack designed to fit Euro rack cabinets. Two rack widths are available: a. 19 inch with 17 card slots to house up to 16 Channel Control Cards and an Engineering Card. b. Half 19 inch with nine card slots to house up to eight Channel Control Cards and an Engineering Card.
PRINCIPAL FEATURES
The 5701 Series Control System is part of the System 57 family and is designed to monitor field mounted industrial gas detectors. The principal features of the system are: * Provides up to 16 channels of gas detection in a standard 19'' subrack using a 3U card format. * Provides up to eight channels of gas detection in a half 19'' subrack using a 3U card format. * Racking available for both front and rear access field wiring. * Simple field connections for wire up to 2.5mm2 . * Single channel mode of operation for high integrity systems. * Channel Control Cards removable without disturbing other wiring. * Catalytic bridge or 4 - 20mA input. * Optional alarm change-over relay outputs. * Multi-alarm mode for master, zoned and voted alarms.
Each sub-rack contains an Engineering Card
and a DC Input Card to make up the rack system The system is designed to meet the differing customer wiring configurations and to achieve this the control functions are split away from the relays and field wiring connections. A single channel of gas detection therefore consists of: a. Sensor Drive Module In order to achieve compatibility with a range of different inputs and sensor types, the circuitry necessary to control the sensor is housed on an independent plug-in Sensor Drive Module. These modules plug directly into a Channel Control Card and are factory fitted. There are two different modules, one for catalytic inputs and one for 4 - 20mA inputs. b. Single Channel Control Card Each Single Channel Control Card functions independently and contains all the necessary electronic circuitry to provide the sensor drive, alarm detection and gas level display for that channel of gas detection
