HONEYWELL 05701-A-0330
The 5701 Series Control System is part of the System 57 family and isdesigned to monitor field mounted industrial gas detectors. The principalfeatures of the system are:*Provides up to 16 channels of gas detection in a standard 19” sub-rack using a 3U card format.*Provides up to eight channels of gas detection in a half 19” sub-rack using a 3U card format.*Racking available for both front and rear access field wiring.*Simple field connections for wire up to 2.5mm*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.*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 arigid custom rack designed to fit Euro rack cabinets. Two rack widthsare available:a.19 inch with 17 card slots to house up to 16 Channel Control Cardsand an Engineering Card.b.Half 19 inch with nine card slots to house up to eight ChannelControl Cards and an Engineering Card.Each sub-rack contains an Engineering Card and a DC Input Card tomake up the rack systemThe system is designed to meet the differing customer wiringconfigurations and to achieve this the control functions are split awayfrom the relays and field wiring connections. A single channel of gasdetection therefore consists of:a.Sensor Drive ModuleIn order to achieve compatibility with a range of different inputs andsensor types, the circuitry necessary to control the sensor ishoused on an independent plug-in Sensor Drive Module. Thesemodules plug directly into a Channel Control Card and are factoryfitted. There are two different modules, one for catalytic inputs andone for 4 – 20mA inputs.b.Single Channel Control CardEach Single Channel Control Card functions independently andcontains all the necessary electronic circuitry to provide the sensordrive, alarm detection and gas level display for that channel of gasdetection.c.Field Interface or Relay CardThe Field Interface/Relay Cards provide the interface connectionsbetween the Control Cards and their respective field connectedgas sensor. In addition, Relay Cards provide alarm outputs to thefield connections
