About this file
The document is a product catalog sheet for the SSM-LE Series Enhanced NEMA Signal Monitor, produced by Eberle Design Inc. (EDI), a manufacturer of traffic signal control system components located in Phoenix, Arizona. The catalog details two models - SSM-6LE and SSM-12LE - which are designed for traffic signal monitoring and are manufactured and tested in the United States, with ISO 9001:2008 registration.
The product offers advanced traffic signal monitoring capabilities with multiple configuration options, including 6-channel and 12-channel versions with either EIA-232 or 10/100 Ethernet ports. Key features include full intersection LCD display, event logging, signal sequence history, true RMS voltage sensing, and compatibility with NEMA TS1 standards. The monitors provide comprehensive fault detection capabilities such as conflict monitoring, red fail detection, clearance monitoring, and AC line monitoring. Additional innovative features include LEDguard signal thresholding and support for Flashing Yellow Arrow PPLT operations. The devices are designed to help traffic signal technicians detect, diagnose, and repair cabinet malfunctions with high reliability and detailed diagnostic information.

SSM-6LE AND SSM-12LE SERIES
ENHANCED NEMA SIGNAL MONITOR
EDI continues to set the industry standard and provide traffic signal professionals with reliable, high quality mission critical component products that improve the performance and lifecycle of traffic control systems.
Providing the signal technician with powerful monitoring and trouble-shooting tools helps ensure that cabinet malfunctions are detected, diagnosed, and repaired with confidence. The Full Intersection LCD display and event log recording capabilities present the signal technician with detailed and accurate information regarding cabinet operation. True RMS voltage sensing makes the SSM-LE series the most reliable signal monitor available at any cost.
Model Options:
SSM-6LE 6 channel capability with EIA-232 Port SSM-6LEip 6 channel capability with 10/100 Ethernet Port SSM-12LE 12 channel capability with EIA-232 Port SSM-12LEip 12 channel capability with 10/100 Ethernet Port
SSM-LE ENHANCED FEATURES
NEMA TS1 Standard:
The SSM-LE series meets all specifications of NEMA Standard TS-1 1989 R2000, Part 6. Basic fault coverage includes Conflict, Red Fail, CVM, 24V-I and 24V-II.
Dual Indication Monitoring detects simultaneous active signals on a channel.
Clearance Monitoring assures proper sequencing of signals and a minimum yellow clearance interval.
AC Line Monitoring responds to low AC Line voltages as well as interruptions.
Full Intersection & Status Display: High contrast, large area Liquid Crystal Displays (LCD) show full intersection status with an active Red, Yellow, Green, and Walk indicator for each channel. Separate indicators identify channels involved in the fault.
Event Logging: The SSM-LE series maintains a nonvolatile event log recording the complete intersection status as well as previous fault events, AC Line events, configuration changes, monitor resets, cabinet temperature and true RMS voltages for all AC inputs. A real time clock time stamps each log event with time and date.
Signal Sequence: The five Signal Sequence History Logs stored in nonvolatile memory graphically display up to 30 seconds of signal status prior to each fault trigger event with 50ms resolution to ease diagnosing of intermittent and transient faults.
EDI RMS-ENGINETM: A DSP coprocessor converts ac input measurements to True RMS voltages, virtually eliminating false sensing due to changes in frequency, phase, or sine wave distortion.
Configuration Options: Front panel options include GY Dual Indication, LEDguard, +24V and CVM Latching, Red Fail Walk Disable, External Watchdog input, CVM Log Disable, and FYA Mode.
Communications to PC or Remote Traffic Management Center:
An EIA-232 or optional 10/100Mbps Ethernet port provides access by a local PC or remote TMC running ECcomTM Windows based software for status, event log review, and archival.
Flashing Yellow Arrow PPLT: The SSM-LE series supports MUTCD Flashing Yellow Arrow PPLT operation with two different modes for TS-1 cabinet configurations.
LEDguardTM: This EDI innovative signal thresholding technique can be used to increase the level of monitoring protection when using LED based signal heads.
