New comprehensively equipped weighing indicator models

With an auto-switching AC supply or optional battery power for mobile equipment use, maximum durability is ensured with an IP67 rated stainless steel housing and mounting fixtures. A menu driven user interface includes a membrane keypad with 12 numeric keys + 7 functional keys that allow straightforward selection of built-in weighing and counting modes where an Alibi memory retains the last 100k transactions.

As standard, the units offer selectable digital I/O, four dry-relay outputs and two opto-isolated inputs for setpoints and batching. PC or PLC connectivity includes an RS 485 full duplex interface or an optional Ethernet TCP/IP and USB 2.0 board can be specified. Two serial ports also provide printing, networking and other various serial streaming formats. A 20mA serial port is available for a remote display. The indictors will drive up to 10x350Ω load cells (4 to 6 wires) or up to 20 units of 700Ω.

The many application configuration possibilities for the 20i and 22i include but are not limited to the following:

• Custom ticket printing with gross, net and setpoint in a customisable format that can include print time and date, unit ID, and consecutive ticket number
• Accumulation where weights are totalled with an armed print function
• Batching with up to eight batch steps with latched or continuous outputs for gross, net and delay setpoint.
• Actions include trip high or low, wait for standstill, print, accumulate and tare
• Keyed tare—pre-set tare value can be entered when the gross weight is at zero
• Configuration for local/remote where the remote unit displays weight and transmits key press commands to the local unit
• User and operator password protection
• Audit trail tracking
• Time and date.
