Telecontrol I/O Modules support SMS-based monitoring, control.

Press Release Summary:

Replacing wiring and radio-based data transmission, TO-PASS® modules provide I/O monitoring, error-reporting, and supplementary I/O control via bidirectional SMS messaging. TO-PASS 761-110 Entry-Level Router and 761-216 MODBUS Master utilize quad-band GSM(TM) modem for basic cell service, while GPRS supports packet-based data transmission. With 0.1% accuracy, eight 12-bit digital inputs send 8 different error messages via email or fax. User-defined text switches digital outputs on/off.

WAGO's All-New TO-PASS® Compact TeleControl I/O

GERMANTOWN, WI - WAGO Corporation's TO-PASS ® Compact Telecontrol Modules provide I/O monitoring, error-reporting and supplementary I/O control via bidirectional SMS (text) messaging. Blending an industry-proven platform with cellular protocols, TO-PASS® replaces resource-intensive wiring and radio-based data transmission with SMS-based controls. Eliminating wiring and radio repeaters (needed to combat line-of-sight limits), TO-PASS® brings SCADA-style capabilities to existing applications and creates new ones.

TO-PASS® 761-110 Entry-Level Router and 761-216 MODBUS Master utilize a quad-band Global System for Mobile Communication (GSM(TM)) modem for basic cell service. General Packet Radio Service (GPRS) supports packet-based data transmission. Units carry UL, FCC and AT&T Network approval for use on the same network millions use daily. An industry-ready platform and approvals assure performance and eliminate concerns about interoperability and protocol compatibility.

The modules' eight digital inputs (12-bit and 0.1% accuracy) send eight different error messages via e-mail or fax. Applying voltage to the digital inputs enables text messages to be sent to up to four user-designated receivers. This ensures security and accommodates preventive measures with designated phones (e.g, passcodes and lockdown). Up to four outputs can be connected to TO-PASS® via SMS. User-defined text switches digital outputs on/off; TO-PASS® texts a confirmation upon command execution.

Beyond factory-default DI/DO On/Off commands, users can customize command text (e.g., Lights On) via dedicated configuration software. Inputs and outputs can be fine-tuned - set scaling from 0-20 or 4-20mA, or the base rising/falling edge on set points. A text then notifies one party if thresholds are met and another if values are too low.

WAGO is the leader in spring pressure connection technology that eliminates loose wires resulting from vibration and temperature cycling, while providing highly reliable, corrosion-resistant and maintenance-free connections. Products: DIN-rail, PCB and chassis mount terminal blocks; signal conditioners; the WAGO-I/O-SYSTEM and more.
