Frequently Asked Questions

What safety integrity levels do the POINT Guard I/O safety modules support?
The modules meet requirements up to and including SIL CL 3 and PLe, Cat. 4 as defined in IEC 61508, IEC 61511, IEC 62061, and ISO 13849-1.
Which controllers are compatible with these POINT Guard I/O safety modules?
The modules can be used with GuardLogix, Compact GuardLogix, and SmartGuard controllers.
How many terminal bases are needed to install each POINT Guard I/O module?
Each POINT Guard I/O module requires two terminal bases. Acceptable catalog numbers are 1734-TB or 1734-TBS (two assemblies) or 1734-TOP, 1734-TOPS, 1734-TOP3, or 1734-TOP3S (one-piece bases). The 1734-TB3 and 1734-TB3S must not be used.
What is the operating temperature range for these modules?
The operating temperature range is -20 °C to +55 °C (-4 °F to +131 °F), tested per IEC 60068-2-1, IEC 60068-2-2, and IEC 60068-2-14.
What type of DIN rail is required for proper grounding?
The product must be mounted on 35 mm (1.38 in.) wide zinc-plated yellow-chromate steel DIN rail to help assure proper grounding. DIN rail must be secured to the mounting surface approximately every 200 mm (7.8 in.) with end-anchors used appropriately.
What does the 'K' suffix in a catalog number indicate?
A catalog number ending in 'K' indicates the conformal coating option, for example 1734-IB8SK.
What isolation voltage is specified for these modules?
The isolation voltage is 50V continuous, Basic Insulation Type between the field side and the system. There is no isolation between individual channels. This is tested according to UL 61010-1.
