Sunny RFGuard System - Remote Unit (RU) with 4 x Relay Input, 4 x Relay Output – Electric Type Model: RFG-ZDW-4I4O(E) RFG-ZDW-4I4O(E) uses dry contact of relay input interfaces to detect on/off condition of external input devices. The input activation can generate remote alarm to Master Unit (MU), and change on/off condition of relay output interfaces to control external devices based on the pre-set logic combination of relay inputs. Both RFG-ZDW-4I4O(E) and external devices are isolated between each other to keep their physical and electrical independence. For long term operation, stability is the key success factor. The hardware design can work properly with critical environment in EMC, safety and IP65 condition. In addition, the design implements watch dog and standby battery to let the hardware work safety. Also the polling feature between MU and RU can make sure the communication link under healthy condition. Highlight Support 4 x NC/NO Relay Inputs and 4 x NC/NO Relay Outputs Relay Output supporting different logic combination from Relay Input Remote alarm and polling by SMS / Wireless data / Ethernet Back up battery, IP65, EMC, Safety protection for long term operation Implement watch dog to avoid abnormal operation Block Diagram IP65 Cabinet Relay I/O Board Local Control Remote control, monitoring or alarm report by Ethernet 2-pair relay inputs (Normal Open) USB port 2-pair relay inputs (Normal Close) Ethernet port (Opt) 2-pair relay outputs (Normal Open) 2-pair relay outputs (Normal Close) RFG-ZDW-4I4O(E) Modem for SMS/ wireless data Back up battery AC/DC PSU Fixed Antenna for Modem Remote control, monitoring or alarm report by SMS or wireless data 220V AC ___________________________________________________________________________________________________________ Sunny Telecom Services Limited, Unit 09, 15/F, Block B, Hi-tech Industrial Centre, 5-21 Pak Tin Par Street, Tsuen Wan, Hong Kong Web Site: www.rfancillaries.com, Tel: +852-2611-9016 Fax: +852-2611-9397 Specification Relay input Input Trigger mode Relay output Output Trigger mode Relay outputs status when All power OFF Internal modem supporting frequency bands Nos of SIM card Local control interface Remote control Internal battery Waterproof Power supply Maximum power consumption Size Operating temperature Relative humidity Weight Normal open x2, Normal close (Ground) x2 Max. 5VDC, 1A not damage Level Trigger Normal open x2, Normal close x2 Max. 60VDC, 2A not damage No AC Power No Battery Power Logic (AND/OR/NAND/NOR) Combination of Relay Inputs Back to default status 850/900/1800/2100/2600MHz GSM, WCDMA and LTE One USB (inside cabinet) SMS (standard) Wireless data (option: RFG-WD) Ethernet (option: RFG-ETH) 7.2V 2200mAh Li-ion IP65 cabinet 220V AC ≤20W TBAL -20 to +60°C 5 to 95% 7kg Ordering Information RFG-ZDW-4I4O(E) - Remote Unit (RU) with 4 x Relay Input, 4 x Relay Output, Electrical Version Option: RFG-WD – Remote Control by RF modem (wireless data)* (Fixed IP needed for MU) RFG-ETH –Remote Control by Ethernet* *Order either option only Technical data are subjected to change without notice – File: RFG-ZDW-4I4O(E) datasheet 2017V1.0 ___________________________________________________________________________________________________________ Sunny Telecom Services Limited, Unit 09, 15/F, Block B, Hi-tech Industrial Centre, 5-21 Pak Tin Par Street, Tsuen Wan, Hong Kong Web Site: www.rfancillaries.com, Tel: +852-2611-9016 Fax: +852-2611-9397
