750-491 WAGO Industrial Automation Components

Wago 750-491 is an I/O unit designed as a standard analog input slice module specifically for weighing or force measurement applications. It operates with a supply voltage of 5Vdc provided by the system and does not require an AC supply voltage. This unit features push-in spring cage-clamp connections for easy installation and is compatible with a DIN-35 rail for mounting. It is designed to operate within an ambient air temperature range of 0°C to +55°C and can be stored in temperatures ranging from -40°C to +85°C. The 750-491 supports an IP20 communication protocol and has a rated insulation voltage of 12 mm. Its dimensions are H100mm x W12mm x D69.8mm, and it is housed in a polycarbonate (PC) / Polyamide (PA) 6.6 casing. The module offers 1 x analog input (load cell) with a mechanical resistance of -15...+15mV / 16-bits / 500ms conversion time and a maximum continuous operating voltage with a 50Hz filter. It has a power dissipation/losses with shock resistance according to EN 60068-2-27 of --15g and a climatic resistance of 95% relative humidity (non-condensing). The control circuit rated current is ±30μ, and it has a maximum temperature measurement error of ±10mV. The unit's response time is 500 ms, and it is designed to withstand a maximum of 65mA (5Vdc from the system supply).
