Touchpoint Pro Gas Detection Control Panel

Touchpoint Pro makes it simpler to design, install, configure and operate a gas detection control system. Built on input/output modules, Touchpoint Pro adapts to projects of every size.

Touchpoint Pro is designed for applications that demand high standards such as SIL 2.

The hardware mounts in a standard electrical panel or a standard rack cabinet. Thanks to its modular flexibility, Touchpoint Pro suits everything from small projects to large, complex ones

System structure

According to the manufacturer, every Touchpoint Pro system is built from four blocks: a central controller with a colour touch screen, plug-in input/output modules, a backplane power and communications rail, and plug-in power supplies. They mount in cabinets or racks and can be mixed freely, so centralised, distributed (remote I/O) or mixed topologies are all possible.

• Input modules: 4-20 mA analog, mV-bridge analog (catalytic flammable sensors) and digital; output modules: relay.
• The backplane rail holds 5, 7, 9 or 10 modules depending on the power supply and enclosure version.
• 24 Vdc power supplies of 120 W, 240 W or 480 W; a redundancy module and a UPS module that charges a back-up battery.
• The ring network has two loops transmitting in opposite directions (Ring A and Ring B) and is self-healing: a failed module is detected and located without affecting the rest of the system.

Integration and interfaces

• The controller carries a Honeywell Analytics sensor catalogue for quick channel set-up; a PC can connect over Ethernet, with optional configuration software.
• Web server when networked: view status and event history, acknowledge, reset or inhibit channels; not for configuration or calibration.
• Optional redundant control centre board (CCB) that takes over if the master fails; optional Modbus RTU interface board with dual redundant RS-485.
• Compatible with most third-party flame detectors, gas detectors and manual call points.

Functional safety

The manufacturer states that Touchpoint Pro is designed to meet SIL 2 requirements (IEC/EN 61508), with its engineering process and components independently verified.

What to send for a quote

• Number of input channels by type (4-20 mA, mV-bridge, digital) and the detectors planned.
• Number of output relays and the logic to control (sounders, beacons, valve shutdown, fans).
• Mounting: wall cabinet, 19 in. rack or floor-standing cabinet; whether remote I/O is used.
• Power supply rating, UPS and battery; need for the redundant board and Modbus RTU.
