Configured to interface with standard 4-20 mA HART loop protocol environments and discrete dry contacts, each channel draws between 3 mA and 8 mA to sense loop status. Integrated diagnostic sub-circuits constantly track the wiring condition to register open circuits, short circuits, and line faults directly into the Experion PKS system register tables, while the internal processing hardware switches between a 20 ms standard scan and a 5 ms fast scan frame rate.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the module differentiate between a standard open contact state and a broken field wire fault?\u003c\/p\u003e\n\u003cp\u003eA: The onboard diagnostic engine continuously monitors the current parameters of each loop. When a line fault detection profile is configured, the channel distinguishes an open circuit condition from a normal open switch state by evaluating the residual leakage current thresholds on the input line.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 8C-TDOLA1 process pulse accumulation signals from high-speed flow meters?\u003c\/p\u003e\n\u003cp\u003eA: The hardware supports a fast scan mode of 5 ms, making it suitable for standard status monitoring and low-frequency pulse detection. For high-frequency pulse acquisition exceeding the 5 ms sampling boundary, a dedicated counter module must be used to prevent missed state transitions.\u003c\/p\u003e\n\u003cp\u003eQ: Is external power required to energize the dry contacts connected to this module?\u003c\/p\u003e\n\u003cp\u003eA: The input channels are designed to interface with 24 VDC loops. The wetting voltage must be derived from the system baseplate distribution or a coordinated external 24 VDC power supply connected to the input termination assembly.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the module assembly vertically onto the matching Series 8 rack or DIN-rail baseplate, ensuring that the high-density backplane pins align correctly before applying pressure to seat the module locks. Maintain clear boundaries around the housing unit to prevent the surrounding ambient cabinet temperature from exceeding the +55 deg C operational limit.\u003c\/p\u003e\n\u003cp\u003eElectrostatic fields modify internal solid-state parameters. Field technicians must attach a verified ESD wrist strap to a grounded chassis point before handling the component or altering terminal connections.\u003c\/p\u003e\n\u003cp\u003eSecure all sensor and switch wiring using the integrated compression terminal blocks, avoiding excess bare wire exposure outside the clamping cage. Route all low-voltage 24 VDC discrete input lines through separate wire ducts away from high-voltage AC motor lines to eliminate electromagnetic cross-talk across the 1500 VDC isolation boundaries.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":43868222914659,"sku":"8C-TDOLA1","price":676.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/361_0f25f20c-aa5f-4616-b207-3f00540de26a.jpg?v=1764723884","url":"https:\/\/www.autocontrolglobal.com\/products\/honeywell-experion-pks-8c-tdola1-51307141-175-digital-input-module","provider":"AutoControl Global","version":"1.0","type":"link"}
