NI TBX-2809 Terminal Block
The NI TBX-2809 (Part Number: 781420-09) is a DIN-rail mountable, unshielded Terminal Block. This Terminal Block is designed to work with screw terminal connectivity. The TBX-2809 offers direct connections to the resources of a compatible NI SwitchBlock Card. This Terminal Block has a safety function consisting of an interlock resistor which allows or disallows connections to the analog bus of the SwitchBlock Card through safety relays.
The maximum current for the NI TBX-2809 is 1 A. The maximum voltage is 150 V. This Terminal Block accessory can easily be mounted onto a DIN rail through a gentle push. Dismantling the Terminal Block from the rail can be achieved with the help of a flathead screwdriver. National Instruments recommends the SH96F-96M-NI Cable for connection between the TBX-2809 and the associated SwitchBlock Card. This screw terminal Terminal Block is compatible with two sizes of DIN rails: EN 50 022 and EN 50 022.
