We ship via UPS and fastest delivery is with Next Day Air. UPS Next Day Air Early typically gets their product to them as early as 8am, Next Day Air gets their product typically there by 10:30am and Next Day Air Saver typically by 3pm. We ship same day for in stock items and the lead time is up to one week for out of stock items. Delivery is dependent on UPS and your shipping method.


The 87026PW is a multifunction module that includes 6 analog input channels, 2 analog output channels, 2 digital input channels, 2 digital output channels. It provides a programmable input range on all analog input (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0 ~ 20 mA or 4 ~ 20 mA), analog outputs are 12 bit at +/-5 V, +/-10 V, 0 ~ 20 mA or 4 ~ 20 mA and all digital outputs can be set as alarm output. Each analog input can be confi gured for an individual range and provides a high overvoltage protection of 240 Vrms. Voltage and current inputs/outputs are jumper selectable.
