TOC-30 Node

TOC-30 Node, Addressable Interface To Third Party Devices The TOC-30 series addressable I/O nodes complement IGD’s addressable gas detection systems. The nodes provide an addressable interface to third party devices. The nodes are equipped with two independent relay outputs and two independent analogue signal inputs. Each I/O point has its own unique system address. This allows the relays to be assigned from a TOCSIN series control panels for alarm signalling, audio visual inputs ect. The analogue inputs can be used to interface with third party equipment such as pressure, temperature, flow transmitters ect. These can then be read back addressabley onto a TOCSIN series controller in the same manner as any standard addressable IGD gas detector. Alarms can be assign to these inputs in the same manner as a standard IGD addressable gas detector. Nodes are available in both safe area and ATEX/IECEX versions, putting control logic where it is needed and minimising cabling.
