Configurable safe small controllers PNOZmulti 2, expansion module, 4 safe analogue inputs 4..20 mA, can be used individually, two inputs can be used simultaneously up to SIL 3/PL e. Expansion module for right-hand connection to a base unit PNOZmulti 2 (PNOZ m B0 or PNOZ m B1). 4 independent safe analogue current inputs, each input can be configured separately. Current range: 4 . 20 mA, measuring range: 0 . 25 mA. Resolution: 15 bits + sign bit, sampling rate: 10 kHz. Working range monitoring in accordance with Namur NE 43 (range limits are freely configurable). Limit value/range monitoring (limit values are freely configurable), max. 12 expansion modules can be connected to the PNOZ m B1, max. 6 to the PNOZ m B0. Safety-related characteristics: depending on the application, up to PL e according to EN ISO 13849-1 and up to SIL CL 3 according to EN/IEC 62061. Exact analog values can be passed on to a higher-level controller via fieldbus for diagnostic purposes. Visualization via the web-based software PASvisu. Validations: TÜV. Dimensions (H x W x D) in mm: 101.4 x 22.5 x 120. Can be configured using the software tool PNOZmulti Configurator, from version 10.8. A separate module program (mIQ) with 256 connection lines can be configured for each expansion module. The user program then consists of a main program and one or more module programs. The module program is structured like the main program and is configured in the same way. The analog module elements are configured directly in the module program. Processing takes place decentrally in the module.
